The crusher machines of the crushing step may employ use jaw crusher, impact crusher, cone crushing, hammer crusher, sand maker. The artificial sand size different, the …

Manufactured sand is also known as artificial sand. It is made from hard granite or quarry stones. Hard stones are crushed into uneven sand-sized angular shaped particles, swept and washed to be finely graded so they are easier to use as construction aggregate. M-Sand is manufactured in three stages: First, vertical shaft impact crushers crush ...

CDE M-Sand is always consistent and always in-spec, leading to higher product quality and lower cement cost. This also helps lower your use of CO2 as part of the production process. Our washing solutions are helping companies provide a range of manufactured sands and aggregates including C-33 concrete sand and No.4 manufactured sand. LET'S TALK.

Reason 2: River sand mining causes tailings. In the process of mining river sand, it often produces a large amount of tailings which is not used reasonably. Especially in small mines, the tailings are piled up at random, occupying land and polluting the environment. Reason 3: A lot of construction waste is wasted.

The use of manufactured sand makes sense from various perspectives. First, manufactured sand is more uniform in structure compared with natural sand. It also has an advantage when it comes to concrete production, because manufactured sand is less needed in the concrete mix by a margin of 5 to 20% compared with natural sand to …
